Abstract (en)
A rotor assembly in a rotating electrical machine comprising: first and second rotor coils, each of said first and second rotor coils comprising a stack of coil straps including a bottom coil strap; a first crossover connection joint integrally extending from said bottom coil strap of said first rotor coil having: a first body member; a first crossover-side connector arm; and a first shoulder that integrally couples said first crossover-side connector arm to said first body member so as to space said first crossover-side connector arm away from said bottom coil strap of said first rotor coil; a second crossover connection joint integrally extending from said bottom coil strap of said second rotor coil having: a second body member; a second crossover-side connector arm; and a second shoulder that integrally couples said second crossover-side connector arm to said second body member so as to space said second crossover-side connector arm away from said bottom coil strap of said second rotor coil; and a rotor pole crossover having a first crossover leg coupled to said first crossover-side connector arm and a second crossover leg coupled to said second crossover-side connector arm so as to position said rotor pole crossover between said first and second crossover connection joints.
